Checking Chain Lubrication; Chain Brake - Stihl MS 441 C-M Manual De Instrucciones

English

Checking Chain Lubrication

The saw chain must always throw off a
small amount of oil.
NOTICE
Never operate your saw without chain
lubrication. If the chain runs dry, the
whole cutting attachment will be
irretrievably damaged within a very short
time. Always check chain lubrication and
the oil level in the tank before starting
work.
Every new chain has to be broken in for
about 2 to 3 minutes.
After breaking in the chain, check chain
tension and adjust if necessary – see
"Checking Chain Tension".

Chain Brake

Locking chain with chain brake
in an emergency
–
when starting
–
at idling speed
–
The chain is stopped and locked when
the hand guard is pushed toward the bar
nose by the left hand – or when brake is
activated by inertia in certain kickback
situations.
Releasing the chain brake
Pull the hand guard back toward the
N
front handle.
NOTICE
Always disengage chain brake before
accelerating engine and before starting
cutting work. The only exception to this
rule is when you check operation of the
chain brake.
High revs with the chain brake engaged
(chain locked) will quickly damage the
powerhead and chain drive (clutch,
chain brake).
The chain brake is designed to be
activated also by the inertia of the front
hand guard
if the forces are sufficiently high. The
hand guard is accelerated toward the
bar nose - even if your left hand is not
behind the hand guard, e.g. during a
